Glass comprising of P₂O₅–Al₂O₃–Na₂O–ZnO is melted in microwave (MW) heating as an alternate energy efficient heating method. Properties of glasses obtained from MW heating are compared with that of glasses prepared adopting resistive heating. Glass transition temperature (T_g) in MW melted glass is found ~ 15–20 °C lower compared to the glass prepared in resistance furnace. XPS O1s spectra indicate less non-bridging oxygen (NBO) formation in glass obtained from MW melting. This may be due to less evaporation as well as less leaching of alumina from crucible wall during melting. Photoluminescence spectra of Eu³⁺-doped glass indicate higher asymmetric ratio in the conventional glass. MW melting requires 2 h 20 min, whereas it is ~ 6 h in resistive heating. Comparison of power consumption analysis depicts maximum MW forward power < 1.5 kW with ~ 1 kW average power during melting of glass. Maximum power in resistive heating furnace is recorded 4 kW for identical melting.

由P ₂ O ₅ -Al ₂ O ₃ -Na ₂ O-ZnO组成的玻璃在微波（MW）加热中熔化，作为一种节能的替代加热方法。将通过MW加热获得的玻璃的性能与采用电阻加热制备的玻璃的性能进行比较。发现与熔融炉中制备的玻璃相比，MW熔融玻璃中的玻璃化转变温度（T _g）低约15–20°C。XPS O1小号光谱表明在从MW熔化得到的玻璃更少的非桥接氧（NBO）的形成。这可能是由于熔融过程中较少的蒸发以及氧化铝从坩埚壁中的浸出较少。Eu ^3+的光致发光光谱掺杂玻璃表明常规玻璃中较高的不对称比。兆瓦熔化需要2小时20分钟，而电阻加热大约需要6小时。功耗分析的比较显示，玻璃熔化期间最大MW正向功率<1.5 kW，平均功率约为1 kW。对于相同的熔化，电阻加热炉的最大功率记录为4 kW。
